Specification of Letters Patent.

Patented Feb. 18, 1913.

Application mea March 27, '1912. serial No. 686,703.

To all w/tom t may concern Be it known that I, FRANK PUJoL, a citizen ofthe United States, residing in St.l Charles county, State of Missouri,have invented a certain new and useful Lamp- Burner, of which thefollowing is such a full, clear, and exact description as will enableany one skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, forming part ofthis specification.

My invention relates to lamp burners and more particularly to that classof burners used in connection with block or switchsignals which areintended to burn as long as possible without trimming.

In the burners of the class above referred to, it is necessary to use around wick in order to obtain the feature of long burning withouttrimming. It is, however, desirable to have the Haine of such lamps latsuch as is produced by a flat wick.

The main obj ect of my present invention is to procure a flat flame andat the same time retain the use of the round wick.

In the accompanying drawings, which illustrate one form of burner madein accordance with my invention, lFigure 1 is aV side elevation, thechimney being shown inb section, Fig. 2 is a top plan view, and Fig. 3is a detail view showing the auxiliary wick tube and the parts attachedthereto.

Like marks of reference refer to similar parts in the several views ofthe drawings.

5 represents the body of the burner which is provided with the usualthreaded nipple 6 for engagement with the lamp font; extending upwardlyfrom the body 5 is a main wick tube 7 through which passes thek usualround wick 8 controlled by the usual shaft 9; surrounding the main wicktube 7 is an auxiliary tube 10 which projects some distance above themain wick tube 7. As the tube 10 surrounds the tube 7, it is evidentthat the upper part of the wick will have an air space between it andthe tube 10 equal to the thickness of the wall of the tube 7. In orderto provide for the passage of air to this air space and at the same timeto increase elasticity of the tube 10, I provide in the lower end ofsaid tube slots 11 which extend above the end of the main wick tube 7.The upper end of the wick tube 10 is slotted and slightly flared asshown at 12. The auxiliary wick tube is substantially the same as shownin my prior granted to me Sepabove the end of the auxiliary tube 10 areflame spreading wings 13 which are preferably substantially diamondshaped, as shown in F ig. 2. The object of these wings is to spread theflame and thus make it approach the form produced by a flat wick'.Rigidly carried by the tube 10 is a gallery 14. This gallery 14 isprovided with up'- wardly extending spring fingers l5 which may be madeintegral with the gallery 14, as shown in Jghe drawing, or formed in anyother usual manner. These fingers 15 retain the lamp chimney 16 intheusual manner.

Extending downwardly from the gallery 14 are draft shields 17, each ofwhich covers substantially one fourth of the circumference of theburner. Between these shields 17 the gallery 14 is cut away, as bestshown at 18, Fig. 2, so as to leave the draft passages in the gallery atright angles to the wings 13. The drafts will thus be directed insuch amanner as t0 flatten the flame of the burner and assist the wings 13 inthe spreading of the same. As the lingers 16 and the draft shields 17are both carried by the auxiliary tube 10, it will be evident that theflat side of the flame can be directed in any suitable direction byturning the auxiliary wick1 tube without disturbing the body 5 of theburner.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent of the United States is:

1. In a lamp burner, the combination with aA wick tube slotted at itsupper end, of a pair of flame spreading wings extending laterally at apoint above the upper end of said tube.

2. In a lamp burner, the combination with a wick tube, of a pair ofsubstantially diamond shaped flame spreading wings extending laterallyat a point above the upper end of said tube.

3. In a lamp burner, the combination with a wick tube, of a pair offlame spreading wings extending laterally from said tube, a gallerysurrounding said tube, spring arms extending u wardly from said gallery,and draft shiel s extending downwardly from said gallery.

4. In a lamp burner, the combination with a wick tube vof a pair offlame s reading wings extending laterally from sai tube, a

gallery surrounding said tube, said gallery being provided with draftpassages substantially at right angles to said wings, spring armsextending upwardly from said gallery, and draft shields extendingdownwardly from said gallery.

5. In a lamp burner, the combination with a main wick tube, of aremovable auxiliary wick tube surrounding said main wick tube, a gallerysecured to said auxiliary tube, spring arms extending upwardly from saidgallery, and draft shields extending downwardly from said gallery.

6. In a lamp burner, the combination with a main wick tube, of aremovable auxiliary wick tube surrounding said main tube, flamespreading wings extending laterally from said auxiliary wick tube at apoint above its upper end, a gallery secured to said auxiliary tube,spring arms extending upwardly substantially at right angles to saidwings, 30

and draft shields extending downwardly from said gallery.

In testimony whereof, I have hereunto set my hand and atiixed my seal inthe presence of two subscribing witnesses.
